"BURT A. PETERSON, OF ROCKFORD, ILLINOIS, ASSIG-NOR, BY MESNE ASSIGNMENTS, TO EDGAR S. NETHERCUT, OF EVANSTON, ILLINOIS.

WIN'DER.

Application filed December 3, 1919. Serial No. 342,214.

To all whom it mag/Concern.

Be it known that I, BURT A. PETERSON, citizen of the United States, residing at Rockford, in the county of .Vinnebago and State of Illinois, have invented certain new and useful Improvementsin lVinders, of which the following is a specification.

This invention relates to winders of the general type exemplified in Patent No. 1,267,977, dated May 28, 1918. The machine shown in said patent is adapted to rewind bobbins to form cross-wound yarn masses or cheeses, and While the present invention is not necessarily limited to any particular type of yarn mass the invention will be disclosed in connection with a machine for producing cheeses. I

In. the construction shown in the before'-- mentioned patent, means is provided for detecting thefact that a cheese has reached the desired diameter. WVhen such a cheese .is reached by the traveling winder-tending mechanism or traveler. devices are actuated to'preventany more thread from being wound on the cheese. These devices include a pivotally mounted feeler or gage located in position to be carried into engagement with a full-size cheese. It has been found that; a cheese will sometimes lie in the path of the end of the gage and thus prevent the gage from functioning as well as causing breakage as the traveler endeavors to pass the cheese. Various causes may result in a collision between the gage and achee'se; for example, the core on which the cheese is formed may become unlatched from its supporting arm and move laterally into such position as to foul on the adjacent arm and thus be held up in the path of the gage; or a cheese may be so nearly full when passed by the gage that by the time the gage again reaches that unit the cheese will be oversize;-or there may be misadjustment ofthe gage. I

The object of the present invention is to provide means for stopping the travel and the operation of the winder-tending mechanism in case of an improper engagement. of the gage with a cheese and to prevent the winder-tending mechanism from being'reset in operation until the cause of the stoppage has been removed. v

In the accompanying. drawings, Figure 1 is/a fragmental front elevation of a winder embodying the features of my invention.

Fig. 2 is a fragmental elevation taken approximately in the plane of dotted line 2 of Fig. 1. Fig. 3 is a fragmental section view of the gage and a safety feeler cooperating therewith. Fig. 4 is a plan View ofthe gage and the 'feeler. Fig. 5 is a fragmental view of the pivotal mounting for the gage. Fig 6 is a view of a latch comprised in the mechanism.

In the drawings, 2) denotes tubular cores on which yarn is wound to form cheeses 0.

Each core Z2 is removably mounted upon a winder-tending mechanism comprises a roll 1 7 27 8 by means of which each cheese in succession is rotated in the direction to unwind yarn therefrom as a part of'the endfinding operation. In the travel of the framework 89, a cam member 250 passes beneath thearms 30 and acts first to raise said arms and then-lower them so as to place the cheeses upon'the roll 278, after which a roll 301 passes beneath the cheese.

Means is provided for gaging the cheeses while the latter are in contact with the roll 801. This means includes the gage or feeler 505 having a hub 505 .which is pivotally mounted upon a shaft 502% The shaft 502 is mounted .in suitable bearings in the framework 89. On said shaft is a stop arm 502 (Fig.2) which normally rests upon a stop plate 502 whereby the normal posi-.

tion of the gage is determined. \The gage 505 is adjustably connected to the shaft 502 by suitable means, as, for example, that illustrated herein, said connecting means being substantially similar to that disclosed in detail in Patent No. 1,267,977. a

The end 506 of the gage 505 lies in the vertical plane occupied by the series of thrown-outcheeses, and is provided with a beveled surface 506 (Fig. 3) which is adapted to engage a full cheese lying upon the roll 301 whereby the gage 505 is lifted and mechanism, not herein disclosed, is actuated to prevent any more yarn from being wound upon the cheese. The line of arrows in Fig. 1 denotes the relative path of the upper portion of the periphery of a full cheese as the gage 505 approaches it.

In order to stop the mechanism in case a cheese extends above the beveled surface 506, and hence in position to obstruct the travel of the gage, 1 provide a safety feeler lever 650 which is pivotally connected to the gage505 at 651. @ne arm of the feeler lever 650 terminates in a curved plate or broadened portion 652 that lies in advance of the forward end of the gage 506 so as to collide with any obstruction which extends above the path of movement of the beveled surface 506. At the other end of the feelerlever 650 is a cup 653 in which lies loosely one end of a push-rod (55a. The opposite end portion of the push-rod is slidably mounted in an opening 655 in the framework 89 and lies in position to engage a lug 656 on a latch arm 657 which is pivoted to the framework 89 at 658.

The mechanisms on the framework 89 are driven and said framework is caused to travel by power transmitted through a shaft 206. The shaft 206 is driven from a pulley 205 through a friction clutch member 209. The clutch member 209 is arranged to be controlled by means of a hand lever 214:. A contractile spring 216 connected to the hand lever 214 tends to throw out the clutch member 209. On the hand lever 214 is a projection 659 (Fig. 6) which normally lies against a locking shoulder 660 on the latch arm 657. Below the shoulder 660 is a shoulder 661.

The operation is as follows: If a cheese resting upon the roll 801 is not of suflicient diameter to extend into the path of the feeler portion 652 but does stand in the path of the beveled portion 506*, the gage 505 will be swung upwardly, thereby actuating the mechanism that prevents additional yarn from being wound upon the cheese. If, however, the cheese should be of such diameter as to be struck by the feeler portion 652, or if the cheese should be displaced so as to be supported by an adjacent arm 30 (see the cheese UK in Fig. l), the feeler 650 will be swung with reference to the gage 505, where by the push-rod 1 will be forced against the lug 656, thus causing the latch arm 657 to swing upwardly. The lever 2M is thereby released to the action of the spring 216, whereupon the clutch member 209 is thrown out and the carriage 89 stops. The pressure of the push-rod 65% against the lug 656 holds the latch arm 65'? up; consequently, should the operator endeavor to restart the mechanism without first removing the cause of the stoppage, the projection 659 will stop against the shoulder 661 before the clutch member 209 is in effective position. When the cause of the stoppage is removed, the latch arm drops so as to permit the projection 659 to be moved into position behind the locking shoulder 660.
